1. I use an adjustable BEC (built into PDB board) to power the gimbal without a filter.
OK, I will check the PDB in your build thread.
2. 1)It depends on how you feed the battery power to the PDB. Solder both battery wires together and then to Attopilot and you get it all through there. I don't like this setup because there is potential for the power module to fail and then it all falls out of the sky. Ask me how I know. I feed the battery wires separately to the PDB. One set goes through the power module and I just scale it in Mission Planner to show what is theoretically going through both. The other set I have going through the Frsky current sensor so I also get the voltage and current on the Taranis. I find the Frsky to be much more accurate. Yes this is more complicated, it provides redundancy while also creating a few additional failure points. Pick your poison.
Yeah, I was thinking of keeping the Attopilot on just one of the two, then putting a FrSky sensor on the other. It just so happens that I have a couple of the per-cell voltage sensor (this guy as opposed to the current sensor) so I will just plug that into the balance port on the battery that is not routed to the Attopilot.
This reminds me, why do we see people modifying lower rated Attopilots as opposed to just using the 180A?
OK - just an extra cable from the BEC to a free port on the Pixhawk?2) I do have a 5V feed to the Pixhawk rail as redundant power from PDB BEC.
that is my line of thinking too. Seems like if noise is an issue, filtering is still simpler than a whole separate battery (unless I'm missing something).3) Your choice. I feed it from BEC because I don't like dealing with multiple batteries. I'm sure there are arguments against this.
That is exactly the approach I plan to take. I will check them out.I have a 5V and 12V built into the PDB I use (see build thread). You can of course use separate ones. Castle creations are the best IMO. In theory you should have good failsafe options with the Pixhawk and it will come home at the flip of a switch.
Thanks!
